The present invention relates to a food package for cooking, storing and heating of ready-to-eat food. The food package comprises a food container (65), a plastic film (26) for sealing the food package from ambient air and being provided with an opening (16), said food package further comprising an openable and resealable valve membrane (52, 62) of a thermoelastic material covering said opening, wherein an adhesion between the valve membrane (52, 62) and the surface it is applied on is lower in a first area (160) than in a second area, wherein said first area (160) extends in a direction at least between said opening (16) of said plastic film and an edge of said valve membrane (52, 62), such that a canal (60) may be created between said opening (16) and a valve membrane periphery during cooking and/or heating of said ready-to-eat food, wherein the valve membrane has a production machine direction (8) of the thermoelastic material which has a relationship to said direction of said first area such that an angle therebetween is within an interval of 60° to 90°.
A food package for cooking, storing and heating of ready-to-eat food, the food package comprising a food container, a plastic film for sealing the food package from ambient air and being provided with an opening, said food package further comprising an openable and resealable valve membrane of a thermoelastic material covering said opening, wherein an adhesion between the valve membrane and the surface it is applied on is lower in a first area than in a second area, wherein said first area extends in a direction at least between said opening of said plastic film and an edge of said valve membrane, such that a canal may be created between said opening and a valve membrane periphery during cooking and/or heating of said ready-to-eat food, wherein the valve membrane has a production machine direction of the thermoelastic material which has a relationship to said direction of said first area such that an angle therebetween is within an interval of 60° to 90°.
A valve membrane of a thermoelastic material for use in a food package for cooking, storing and heating of ready-to-eat food, said valve membrane being provided with an adhesive such that the adhesive properties in a first area is lower than the adhesive properties in a second area, wherein said first area extends in a direction from an edge of said valve membrane and to a position on the surface of said valve membrane spaced from the periphery of said valve membrane, wherein in use of the valve membrane a canal may be created along said first area, wherein the valve membrane has a production machine direction of the thermoelastic material which has a relationship to said direction of said first area such that an angle therebetween is within an interval of 60° to 90°.
A method of producing a valve membrane for use in a food package for cooking, storing and heating of ready-to-eat food, the method comprising
